Banjo Brothers makes the Commuter Backpack for riders who go out everyday, in any weather. Its roll-top outer is made from ballistic nylon with a welded-seam liner that's utterly waterproof. Wide, padded straps evenly distribute weight comfortably on the bike or off, while chest and waist straps add stability. It sits low on the back to reduce blind spots. And, there are two quick-access side pockets, organizing pockets, a shoulder-strap-mounted phone holder, large reflective stripes, and a taillight tab.
